Test-case triggering the error
I ran into this error trying to compile a large project.
C-Reduce got it down to the attached test-case.
The error is reproducible with
>g++ test.cpp
test.cpp:22:3: warning: access declarations are deprecated in favour of
using-declarations; suggestion: add the ‘using’ keyword [-Wdeprecated]
an::bf;

test.cpp: In instantiation of ‘k<an>::bn()::<lambda(auto:1)> [with auto:1 =
int; an = j]’:
test.cpp:1:66: required from ‘auto ad(a, ac ...) [with a = k<an>::bn() [with
an = j]::<lambda(auto:1)>; ac = {int}]’
test.cpp:27:7: required from ‘bool k<an>::bn() [with an = j]’
test.cpp:39:22: required from here
